It's devastating my poor 512GB SSD is full just three days after I removed the files.
Is there any temporary solution for this?

my current solution is to have a scheduled task that deletes those files periodically. I am doing it for wsl as well as for some outlook trace files that also have the same behaviour. Script here:

Temporary solution, turn off support for GUI applications in WSL:

User can also choose to turn off the system distro entirely by adding the following entry in their .wslconfig file (located at c:\users\MyUser\.wslconfig). This will turn off support for GUI applications in WSL.

[wsl2]
guiApplications=false

I've added this to my .wslconfig but it didn't help

Same issue here, seems like compiled version of RD Client has a bug:

MSRDC_WILFailure : "D:\a\_work\1\s\RdClient\RdClient.SessionHost\exe\msrdc\MSRDCRecoveryManager.cpp",      175, "", "msrdc.exe",    14448,        1,        0, 0x80070002, true
MSRDC_WILFailure : "D:\a\_work\1\s\RdClient\RdClient.SessionHost\exe\msrdc\MSRDCRecoveryManager.cpp",       42, "", "msrdc.exe",    14448,        1,        0, 0x80070002, true
MSRDC_WILFailure : "D:\a\_work\1\s\RdClient\RdClient.SessionHost\exe\msrdc\MSRDCRecoveryManager.cpp",       31, "", "msrdc.exe",    14448,        1,        0, 0x80070002, true

Update: Upon looking into the trace log I found that "EnableMSRDCTelemetry" is missing within registry. I may have fixed the issue by installing Microsoft Remote Desktop MSI (not sure if that works with the AppStore version) followed by system reboot. The error logs for now stopped spamming the RdClientAutoTrace directory.

I discovered I had this issue last night, my 500GB SSD was filled in less than an hour when I walked away from my PC. I tried updating the RD Client as #10216 (comment) mentioned above and that did not fix it for me.

What did fix it for me was adding the following line to .wslconfig as #10216 (comment) mentions.

[wsl2]
guiApplications=false

My WSL version output if it's helpful:

WSL version: 1.3.11.0
Kernel version: 5.15.90.2-3
WSLg version: 1.0.54
MSRDC version: 1.2.4240
Direct3D version: 1.608.2-61064218
DXCore version: 10.0.25880.1000-230602-1350.main
Windows version: 10.0.22621.1992

Last time I know it was working was about a week ago if that's helpful.

I came up with a simple solution that doesn't require disabling guiApplications:

1. Delete the folder %temp%\DiagOutputDir\RdClientAutoTrace
2. Create a txt file under %temp%\DiagOutputDir and rename it to RdClientAutoTrace, make sure you have delete the extension name .txt of the file
3. No RdClientAutoTrace files will be created any more

I just had to delete over 100gb of these files.

This needs to be fixed asap.

[hez2010]

Does this method have a side effect ?

No side effects. Those files are all tracing logs.

I have the same issue, my disk consumed almost all of the usable space overnight.

I deleted following option out of my .wslgconfig (%UserProfile%.wslgconfig)
WSL2_WESTON_SHELL_OVERRIDE=desktop-shell

Now it runs perfect.

I came up with a simple solution that doesn't require disabling guiApplications:

1. Delete the folder `%temp%\DiagOutputDir\RdClientAutoTrace`

2. Create a txt file under `%temp%\DiagOutputDir` and rename it to `RdClientAutoTrace`, make sure you have delete the extension name `.txt` of the file

3. No RdClientAutoTrace files will be created any more

Is it ok to do this? im just asking will it corrupt my wsl?
